IMPROVEMENT IN MACTHINES FOR POLISHING THE HEELS OF BOOTS.

Specification forming part of Letters Patent No. 44,489, dated September 27,1864.

To all whom it may concern:

Be it known that we, JAMES M. THOMPSON and GEORGE P. FRENfiH, of Stonehain, in the county of Middlesex'and'State of Massachusetts, and SETH D. TRIPP, of Lynn, in the county of Essex and same State, have invented a new and usefulI-mprorement in Machines for Polishing the Heels of Boots and Shoesyand we do hereby declare that the following is a full, clear, and exact descrip tion theieof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawings, making part of this specification, in which- '1 Figure 1 represents -our machine in plan. Fig. 2 is a side elevation of the same, the side of the polishing-wheel being turned to the beholder. Fig. 3 is a front elevation of the same.

Similar letters of reference indicate like parts.

A good degree of heat is requiredin bringing the blaokball or wax with which the outside of the heel of too its and shoesis covered to the hardened and polished state which belong-to a good finish. Before machines were applied to this branch of the trade of shoemaking, it was always a laborious part of the making of a boot or shoe to blackball the heel, which was clone by the aidof asteel tool heated at a tire or at the flame of a candle, which-had to be lighted on purpose for this work. In order to lessen the expense and decrease the labor of the workmen in this part of the shoemaking process, we have invented a machine which will enable the workman or workwoman to do rapidly and with little exertion that which was formerly done with great exertion.

A standard, A, which carries the machine,

is firmly secured to the flooring. At a suita-' ble height in the standard to suit the position of the workman I place a shaft, S,,which projects from opposite sides of the standard, so as to secure upon one end a drivingpulley, H, and

upon the other a polishing-wheel, B. A stud, D, is fixed in the standard, beneath the polishing-wheel, and from this a strap of leather or any equivalent material extends around the back part of the polishing-wheel and up to a tightening pin or screw, E, fixed in the standard, above the wheel B. By tightening the screw or pin E the strap G-is strained against the wheel B and the friction produced heats the wheel when it is in motion.

Upon the front of the standard, on a line with the shaft S, is attached a right-angled piece of metal, F, in the position shown in the drawings, so that the projecting side thereof shall lie along the side of the wheel B and project beyond its periphery, as seen in Figs. 1 and 2. r The object of this guard is to furnish a seat against. which the bottom or sole of the heel may rest while the edge of the heel is pressed against the polishing-wheel. In a heel-polishing machine now in use the polishing-wheel has a flange upon it around its whole periphery. One objection to such a wheel is found in the fact that the blacking or wax gets upon the face of, the flange and grinds it into the face of the heel, and another is that greater force is required to be used by the operator because of the greater bearing-surface 0",the wheel.

The wheel B may be of stone or metal, or any other suitable'mateiial.

We claim as new and desire to secure by Letters Patent- 1. Heating the polishing-wheel of heel-p0lishing machines by friction, substantially as described.

Y 2. The independent guard-plate F, in combination with the polishing-wheel B, substantially as described.
